Sometimes I change my mind, I just purchased a nice straight E150 with the 5.8, put a little work into her and took the 1st trip to LBL and all the way down to Memphis TN. Round trip 1815 miles. I drive anything Ford or GM, my pick-up being a Ford Sport Explorer, Daily Driver GMC Yukon and my 1st Van GMC love them all.
The Ford Van, 5.8 with just 17k on her was way underpowered when compared to the 5.7 GMC, the trans always searching up and down when pushed in the higher hills of TN, the 5.8 just did not seem to have the toque of the 5.7, the GMC in the Rockies never had this happen, Ford: just hills of Tennessee, sometimes it's not just the motor but the tranny as well, give it a he!! of a test drive.
The Ford as far as visibillty was better than the GMC by maybe 15-20%, but three other glaring items were the foot space on both the drivers side and pass sides of the Dog House, on a long drive this was murder, the suspension was like a wave ride where the GMC nice and steady/solid (Remember mine was a E150 not E350), than the back doors GMC/GM opening much greater access if your truly looking at the Camp side of the van. By the time you take the frame rails for attachement, factory frame battery boxes, wall bracing for paneling all better in GM's, the Ford would be passed on if it were me hands down.
Meeting a van traveler with a Chevrolet Astro with just 231k on her I made a deal to sell the Ford and was very happy to return to the GMC/Gm product line. I hope that the new owners are happy with her, I was glad to see her go!
